On the 4th July 1776, the Declaration of Independence was signed by the 15 Colonies of Acadia; Bermuda; Carolina; Connecticut; Georgia; Maryland;
Massachusetts; Newfounland; New Hampshire; New Jersey; New York; Nova Scotia; Pennsylvania; Rhode Island; and Virginia; asserting their separation from the United Kingdom and creating the United States of America. During the Revolutionary War, they were joined by Quebec and Vermont, effectively stripping the British Empire of all its colonial possessions in continental North America. Over the course of the next 183 years, the United States grew to encompass 72 states and 9 territories, with the accession of Hawaii in 1959, covering almost the entirety of the North American continent.
The United States has three official languages: English; French; and Spanish; all of which are widely spoken, and is approximately the size of OTL Russia, India, and Argentina combined.
